To all zc/wm t may concern:

Be it lmown that I, Marzo LINCOLN Iznooron, a citizen of the United States, and a resident of Elkhart, in the county of Elkhart and State of Indiana, have invented a new and useful :Improvement in Processes for Forming lVells, of which the following is a full, clear, and exact description.

My invention relates to improvements in processes of pumping, and it consists in the steps hereinafter set forth.

An object of my invention is to provide a process by means of which water in strata, which is composed of considerable sand, may be pumped, without clogging up the pipes with sand or without delivering sand where it is not wanted.`

A further object of my invention is to providea' process of the type described,

which does not necessitate the provision of,

special apparatus, thus making the process an economical one.

My invention is illustrated in the accompanying drawing, which is a cross section showing the manner in which the invention is carried out.

In carrying out my invention, I make use of a pump 1 of any suitable type, having a delivery pipe 2. This pump may be driven by any suitable device. such as by a belt 3 on-a pulley 4 on the shaft 5 of an engine or motor (not shown). It is desirable to elevate the pump or lower it, and to this end I provide a platform 6 upon which the pump rests, lwith means, such as screw jacks 7, for raising or lowering the platform.

The first operation in preparing for pumping the water is to sink a pipe 8 down through the earth to the water-bearing strata. In the drawing, 9 indicates the surface soil which may consist of dirt and gravel. 10 indicates the usual sub-'stratum of clay, while the water-bearing stratum is indicated at 11. This stratum usually consists of fine sand and clay through which the water seeps. The pipe 8 is filled with water. A pipe 12 is now placed on the inside of the pipe 8 and extends down to the water bearing stratum 11. This pipe 12 connects with the pump l. The pump is started,

and the water in the pipe 8 will idow downwardly and upwardly into the pipe 12. rIhis movement of the lwater will cause the sand near the bottom of the pipe to pass upwardly', and will eventually create a pocket below the lower end of the pipe 12. rilhe pipe 12 is lowered from time to time, until the pocket is extended, as shown at 13. 'llhe pump 1 is now stopped, and the water from l the water-bearing stratum 11 will seep in and lill the pocket 13. .Pipes 14 may now be put down to the pocket, and when the water is drawn through these pipes 14: by any means, such as a pump (not shown), it will be pure and free of sand. Furthermore, there will be little danger of clogging the pipe, due to the fact that the pipes are drawing from the pocket of pure water.

It is obvious that other pipes might be sunk about the central pipe 12,4 so as to pump water, and that the water so pumped will be clean. and free of sand.

If, at any time, the water in the pocket becomes low, or if there are any indications of sand getting to the pipes 14, the central pipe is lowered, and the rocess of enlarging the pocket is proceeded with, as already described. I claim: a L

The herein described process of forming wells, which consists in sinking a pipe down to the upper surface of a water bearing stratum, fillin said pipe with water, lowering a smal er pipe through said first named pipe, through said inner pipe, moving the smaller pipe with respect to the large pipe, whereby the .movement of the water downwardly from the larger pipe and upwardly through the smaller pipe will cause a pocket to form in the under surface of the stratuml which is .disposed directly alcove the water bearing stratum, and in the upper surface of the water bearing stratum, the portion of the pocket extending intoy the water bearing stratum having a cup-Shaped depression that extends below the upper surface of the water bearing stratum so as to permit the water to readily seep into the pocket.
